My avocado tree is two years old and was planted in front yard by itself 14 months ago. It's about 4 ft tall and this morning I noticed several leaves turning black. I don't know if this has anything to do with it but we've had a wet summer but also live in Fl where the soil is basically sandy and weather has cooled slightly over last few days

I don't know what is causing the leaf problem, but if that is a grafted tree, you need to remove that sucker growth at the bottom.

Did you fertilize or give it any soil amendments like manure lately? Sudden heavy rains can release nitrogen from those types of amendments all in one big flush that can burn the leaves.

Or maybe if you have a lawn service, they sprayed some sort of fertilizer around it?

NO I don't give it anything and nothing has been sprayed on it
